The Hydrogen spectrum is the spectrum of hydrogen divided into a number of spectral lines
Explanation:
- In the hydrogen spectrum, electrons de-excite from the fifth excited level to ground level. the ratio of the number of lines from the ultraviolet region to the visible region is equal to 6
- Electron is in the fifth excited state n=6
- Here the transition from n=6 lies in the Lyman series which is found in the Ultraviolet range
- Then the series lies in the Balmer series which is in the visible region
- Then in n=6 and in the fifth excited state, it lies in the infrared region.
